[ all rchom zit may concern: Be it known that I, JOHN T. H. PAUL, a citizen of the United States, residing at Chicago,

. in the county of Cook and State of Illinois,

' which communicates .for use in filtering joined together.

haveinvented a new and useful Improvement in Filters, of which the following 1s a specification. I.

- My/invention' relates particularly to filters liquors and the primary object of the invention is to provide a filter of simple construction having a large ca acity and thoroughly effective to cleanse the iquor passing through it.

he invention is illustrated in its embodiment in whichp Figure Lrepresen ts a broken sectional view of the improved filter, as indicated 1 at linebroken section taken as indicated at line 2 of Fi 1, the various members employed in the fi ter bein brokenaway to indicate more clearly the re ation of the parts; 3, a view of on member of, a collector e ement through which the liquor asses on its way to the central conduitof t e filter; Fi 4, a view of another member of the same co lector element; Fi 5 a broken view illustrating a detail of a ange or outer rim of the pan or referred n the accompanying rawmgs,

casing of a filter-cell; Fig. :6, a broken,bot-' tom view of the same member; Fig. .7, a broken section taken as indicated at line 7 of Fig. 2 and showing a detail of the perforate bottom of the casing or pan of a'filter cell, and Fig. 8 a broken view illustrating the manner in which the two members of the collector element illustrated in Figs. 3 and 4 are The filter comprises in its preferred embodiment a casin A, supplied with an inletpassage-a near-t e and with an outlet 0 at the center of its bottom, andfilter-cells B, contained in the easing and forming therewith an annular chamber B, the cells having a central conduit B,

with the central outletassage a of the casing. The casing Afmay he of any approvedconstruction. As shown, it comprises a c linder a, externally flanged at its ends, an( to and bottom ndscf' a, respectively, detac ably connected with the cylmder.

Each cell B comprises a comparatively hallow circular pan 1), having a perforate the section being taken 1 of Fig. 2; Fig. 2, a;

The

corrugations b, as-shown in Figs. 1 and 7'. The eripheral portion b of the pan 1) is rovide with an inturned flan e b", upon w ich the .peripheral portion of t tom rests andis secured and has a depending flange b", provided with radial grooves or assages 6. (Best shown in Figs. 5 and 6.) ach conduit-section b is provided externally, somewhat above its center, with a flange I)", having on its upper surface an an nular recess or groove 1). of the conduit-section b? extends through a central perforation with which the perforate bottom I) is rovided and is fitted with a bearin -rin flange t e inner margin of the perforate bottom is secured.

This will be better understood by reference to Fig. the member b is fitted within the flange b of the member b, as shown in Fig. 1, the bindingniembers are preferably joined as by soldering. The conduit-sections b", which constitute also inner binding members for the screens, may be joined togetherand ing member 5 up er screen b. is provided at erip ery. The members b" b to the inner margins of the screens by solder.-

When 51 The spacing mem- .bers b 'extend between the conduit-sections 1 b b, so that passages leading to the, central conduit sections b b are provided on their unopposed surfaces with annular recesses or rooves b upon the bottom of the filter-casing, spaces being preserved therebetween for the admission of liquid beneath the cell-pan. The ring b -of the lowermost filteran bears upon a gasket 1), which is slippe upon the- ,conduit-SeCtion b? and bears uponthe bottom of the filter, The conduit-sections b b telescope with the conduit-sections b as shown. Over the top of the filter mass in eachcell is placed aperforate top b The drawings show a two-cell filter; but it will be understood that as many cells may be employed as are desired. Above the topmost cell and bearing against the lower surface of the casing top a is a radially corrugated member b ,equi ped centrally with a conduit-section I), W ich telescopes with the conduit-section b of the uppermost filter-cell and completes the central conduit at its upper end.

It will now be understood that when the filter parts are assembled as shown in Fig. 1 the liquor may pass from the annular chamberB throu h the grooves 12 at the base portions of t e filter-pans, thence through the perforate bottoms and tops of the filterpans and through the filter masse to the collector elements I), through w ich the liquor escapes to the central conduit B In practice filter material is confined between the flanges'b and the conduit-sections and 'the rings b, on the one hand, and the conduit-sections b b, on the other hand, and tightly compacted in the grooves with which the members are provided, thereby preventing; any free escape of the liquor to the central conduit except by way of the collector element. Opposed to the conduit-section b of theupper collector element is a flange b, between which and said conduit-section the filter mass is compacted.

It will be understoodthat by reason of the telescopic connection between the conduitsections at the center of the filter considerable latitude is allowed for compacting the filter masses in the cells when the parts are drawn together bymeans of bolts or by any 7 other well-known means.

What I regard as new, and desire to secure by Letters Patent, i s- 1. In a filter, the combination of a casing provided with an inlet and having a central outlet, and filter-cells within the casing and forming therewith an annular chamber, the filter-cells being constructed with telescoping central conduit-sections and external opposed surfaces at the conduit-sections with filter masses extending between and compacted between said opposed surfaces, for the purpose set forth.
